Abstract

By using time-resolved photoelectron spectroscopy, decay of optically excited states of hydrated Au^- mass-selected in the gas phase was studied. It is suggested that the pump-photon can induce injection of an electron from auride chromophore to the water solvent. The cluster with three water molecules (Au^-(H) showed a long-living excited state with a lifetime of ~19 ± 3 ps, whereas that of Au^-(H)is only ~3 ± 1 ps. The fate of an optically excited state of an ionic species can be significantly changed by the number of water (solvent) molecules attached.
